Rapid detection of donor-dependent photocatalytic hydrogen evolution by NMR spectroscopy.

Understanding molecular processes at nanoparticle surfaces is essential for designing active photocatalytic materials. Here, we utilize nuclear magnetic resonance (NMR) spectroscopy to track photocatalytic hydrogen evolution using donor molecules and water isotopologues. Pt-TiO catalysts were prepared and used for isotopic hydrogen evolution reactions using alcohols as electron donors.
